MACHINE FOR PERFORATING STRIPS FOR. SINGLE-TYPE-CASTING MACHINES.

Specification of Iietters Patent.

Application filed June 3D, 1915. Serial No. 37,404.

To all whom it may concern.

Be it known that I, Gnono AMRHEIN, citizen of Germany, residing atMunich, Bavaria, Germany, have invented certain new and usefulImprovements in Machines for Perforating Strips for Single-Type- CastingMachines; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it ap-pertains to make and use the same.

The present invention relates to the manufacture of perforated stripsfor single-typecasting machines.

The present invention consists of a device for manufacturing suchperforated strips and is mainly characterized by the fact that themarginal perforations are made by means of the pin wheels of the feedmechanism, advancing the paper strips and in one operation with thekeys. For this purpose the unperforated paper strip is guided over aloosely revolving roller, which presses the paper strip against theteeth of the said pin wheels.

In order to render the present invention more easily intelligiblereference is had to the accompanying drawings.

Figure 1 shows diagrammatically partly in section and partly in sideview an apparatus, according to this present invention, while Fig. 2 isa section on line AB of Fig. 1.

Referring to the drawing a. is the standard carrying the apparatus. 12is a supply roll and d an unperforated paper strip, wound off the saidsupply roll I) and e is a winding spool, upon which the paper strip clis wound again after it is perforated. f are jaws, attached to the sidesof the standard a and g are the pinwheels of the feed mechanism, saidpin wheels being loosely rotatable and mounted on either of the saidjaws f, and advancing with their teeth the paper strip as soon as it isperforated. Between the pin wheels 9 there is provided a die cylinder h,which is stationary and open at the top. This die cylinder 72. servesfor the letter perforation and receives the waste material from thepaper strip being pushed through by the punch 11. In front of the pinwheels 9 a sleeve 70 is loosely located, which in the path of the pinwheels 9 is provided with circumferential apertures 1, in which theteeth of the pin wheels engage in such a manner that the said pinwheelsg and the sleeve .70 form, so to say, a gear, between PatentedNov. 2, 1915.

which the unperforated paper strip (Z, which extends over the width ofthe sleeve, is

ipassed. The sleeve is is loosely rotatable aroundan axle m, which isprovidedat its two ends with collars n, which in the path of theapertures 1 contain each acircular groove 0, which is so deep that noresistance is offered to the pin wheels g. The collars 12 may bearranged more toward the middle so that};1 then the grooves 0 may bedispensed wit The sleeve is and its bearing are preferably detachableand the sleeve 70 may be spring pressed so that it may be yieldinglyforced against the pin wheels. For this purpose the axle m is journaledin two plates 79 arranged sidewise of the jaws 7, preferably inrearwardly open slots 7". The plates 12 are loosely suspended on a crossbar 8, so

that when the plates 79 are turned forward. the sleeve is is moved awayfrom the pin wheels 9 and maybe removed. t are adjustable springs, whichact against the plates 79 and the other end of which is attached to thestandard a, so that the suspended parts 79, is may be pressed againstthe pin wheels.

In front of the sleeve 70 there is preferably provided a guiding rollera, which is positioned in the plates 79 and by means of slantinglyupwardly directed slots o, is rendered capable of rotation and of beinglifted.

The unperforated strip (Z, being wound off the roller 1) is passed overthe under side of the roller to, over the upper side of the sleeve k,between the latter and the pin wheels 9 and finally to the winding spoole. As soon as the feeler apparatus is set into operation the teeth ofthe pin wheels 9, engaging the aperture 1 of the sleeve 70, are forcedinto the unperforated paper strip and impress the two rows of holes,which are situated near the edges of the paper strip. Those teeth of thepin wheels, which are in front of the teeth effecting the perforation,at once enter the holes to and advance thanbefore, And-"thisfor thereasonthat the teeth of the pin wheels 9 do not cut holes, allowing moreor less play, but such holes, which exactly correspond to the form ofthe teeth, and. which fit exactly the teeth of the ratchet-wheels. ofthe casting machine.

Should any jerking advancing movement occur when winding off the paperstrip, or should the latter be stopped or hemmed this will becompensated by the yieldingly posithe paper strip (Z, (Z is alwayssomewhat lifted, falls down again in the slots 2; and

."thus draws the paper strip from the sup- 20' plyroll 7).

Paper waste and the like may be removed from the circular grooves 0 byraising the 'sleeve'ic away from the pin wheels 9- and then brushingsuch waste into the interior,

m, of the sleeve is or into a separate receptacle, as desired.

I claim as my 1nvent1on:

-1. In apparatus for the purpose set forth,

the combination of a supply roll adapted to support areel ofimperforated material, we. winding spool adapted toreceive'saidmaterial'after perforation thereof, pin wheels arranged between saidroll and said spool,

and a sleeve adjacent to said pin Wheels, said sleeve havlngperforations into which the teeth of said pin wheels enter, whereby saidpin wheels are adapted to simultaneously feed said material andperforate the "advanceof said sleeve; 1 e In testimony whereof Ihereunto affix my Vitnesses "same in its passages-0m? the fksupply rollto the winding spool.
